Definitions

  • This invention relates to a sanding apparatus, particularly a sanding apparatus with at least one detail sanding point.
  • Sanding apparatus which have platens to which abrasive sanding sheets are attached. Orbital or random motion is applied to the platen by a motor via a central drive. The platen moves in relation to a head of the apparatus.
  • Platens can be of varying shapes, known examples include circular and rectangular platens. Platens for detailed sanding are generally triangular in shape with outwardly curved edges and three detailed points. Iron shaped platens are also known in which a single point is provided for detailed sanding whilst a large surface is provided for general sanding, such as the one disclosed by DE-A-4 444 028.
  • Known sanding apparatus have a body of the platen of a hard plastics material to which a carrier layer is mechanically lockable.
  • the carrier layer bears a Velcro (registered trade mark) connection to which a foam pad, also bearing a Velcro connection is applied.
  • the abrasive sheet can be applied to the surface of the foam pad also by means of a Velcro attachment.
  • platen is used herein to denote the combination of the platen body, the foam pad and any intermediate layer.
  • the points of the foam pads of detail sanding platens often become heated due to extensive use of the point by angling the platen such that only the point of the foam pad is in contact with the surface being sanded.
  • a sanding apparatus comprising a platen with a flat surface to which an abrasive sheet can be attached, the platen having a peripheral edge with at least one tip, for detailed sanding wherein a conductive means is provided through the platen adjacent to the tip and which acts as a heat sink removing heat from the surface.
  • the conductive means is a metal bolt.
  • the metal bolt is flush with the surface of the platen to which an abrasive sheet is attached.
  • the metal bolt attaches the separate layers of the platen together.
  • the separate layers of the platen may comprise a hard plastics material platen body, a carrier layer and a foam pad layer.
  • the foam pad layer provides the surface to which the abrasive sheet is attached.
  • the abrasive sheet is attached to the surface of the platen by means of a Velcro attachment.
  • the portion of the platen adjacent to the tip may be detachable.
  • a sanding apparatus 1 has a platen 2 formed by the layers of the platen body 5, a carrier layer 12 and a foam pad layer 8.
  • the platen 2 has a peripheral edge 7 which has at least one tip 4.
  • Figure 1 shows a platen 2 with a single detail tip 4.
  • Figure 2 shows a platen 2 of a detail sanding apparatus with three tips 4.
  • Motion is applied to the platen 2 by a motor through a central drive 6.
  • the platen 2 moves in reaction to a head of the apparatus 1.
  • the carrier layer 12 is mechanically attached to the platen body 5.
  • the carrier layer 12 bears a Velcro connection.
  • the foam pad layer 8 also bears a corresponding Velcro connection such that the foam pad layer 8 is held on the carrier layer 12 by the Velcro connection.
  • the foam pad layer 8 also carries a Velcro connection on the surface to which an abrasive sheet is attachable. The Velcro surface of the foam pad layer 8 can become worn by the heat generated by the sanding action.
  • a bolt 18 is provided through the platen 2 including the foam pad layer 8.
  • a nut 20 secures the bolt 18.
  • the nut 20 lies flush with the surface of the foam pad layer 8.
  • the nut 20 and bolt 18 are formed of a conductive material such as metal.
  • the nut 20 and bolt 18 act as a heat sink conducting the heat away from the surface of the foam pad layer 8 at the tip 4. The heat can be dissipated throughout the sanding apparatus 1.
  • the nut 20 and bolt 18 provide a securement through the layers of the platen 2 removing the need for a Velcro attachment between the carrier layer 12 and the foam pad layer 8. This is advantageous as during sanding, the connection can be inhibited by dust clogging the Velcro connection.
  • the abrasive sheet can be applied by the Velcro attachment means on the surface of the foam pad layer 8 over the flush surface of the nut 20.
  • the area surrounding the tip 4 of the foam pad layer 8 can be detachable from the remainder of the platen 2.
